well, the wj, 1999-2004 grand cherokee, never came with the 5.2, it has the 4.7 powertech.

you're going from obdii controlled to a pre-obdi vehicle. it's going to be a gauge and wiring nightmare. the axles are useless to you, if it really is a wj. the motor will be quite a tight fit, if it is a wj.
